Last night, in Brussels, eight men allegedly wearing police uniforms and masks cut a hole in a Brussels airport's fence. Driving two vehicles — reportedly a <>white Mercedes Vito and a black Audi sedan, at least one with flashing blue lights — onto the tarmac, they stopped beside a Brinks security vehicle from which men were loading $50 million-worth of uncut diamonds onto a Zurich-bound passenger plane. The eight allegedly brandished machine guns with laser sights. They stole the diamonds. After three minutes they sped away from the plane. And within eleven minutes, they'd driven back through the hole they came in. No shots fired. Gone.

Already, officials have begun to concede that it may have been something of a perfect crime. De Morgen reported that since most of the stolen diamonds appear to have been uncut, there's no corresponding certificate to mark them. That means they can be sold without a trace.

But will it end up as the most perfect diamond heist even in the past decade?

As competition, there's the 2003 heist in Antwerp, Belgium — the world's capital for diamond cutting, and an area widely populated with police and security cameras — where the bandits broke through ten layers of security, including a lock with 100 million potential combinations, and allegedly stole $100 million in diamonds. Police caught the alleged leader, but he's out on parole and talking. They never found the bounty.

There's also the two identical German twins who left only a glove at the luxury department store they robbed in 2009, after climbing into the shop via a rope ladder. But since they were twins, the DNA from the glove matched both of them, and because of something of a double-jeopardy wrinkle in German law (DNA from a single source can't be used to convict two people), neither could be tried for the crime. They walked.

And then there's the 2008 Harry Winston Heist, where four men — three disguised as women, in blonde wigs — stole over a hundred-million dollars of diamonds, rubies, and emeralds. Police believe the notorious Pink Panthers network of thieves performed the heist. Though authorities have never found the members.

As for the eight in Brussels, the police are looking. They've found a van burnt to the crisp. But that's all so far.
